Aww, what a cute scene. I really like this couple (although Haruhi kinda wished for this lol)
It's great to see her smile since most of the time, she's blackmailing, extorting or doing anything out of the ordinary

why do i get this feeling that she stuck herself there after kyon had fallen asleep... :\

still.... smiling, cute haruhi is a nice change every once in a while
